与Pd（II）离子络合后，精确设计的两个三（3，5-吡啶）单元在两端的链状配体组装，与线性模板分子的帮助下，到一个离散的管状配合物的长度为3.5 nm。通过核磁共振谱、冷喷雾电离质谱和单晶X-射线分析，证实了配位纳米管的高稳定性和明确的结构。客体的长度进行了区分的管：当关联的链状客体分子，其中两个联亚苯基单元与（OCH 2CH 2）n连接器连接，进行了比较，管选择性地识别一个适当的客体，其长度是可比的管。四硫富瓦烯（TTF）封端的线性客人直接氧化TTF 2+在管中，但通过TTF+逐步减少管外。
Upon complexation with Pd(II) ions, precisely designed strandlike ligands with two tris(3,5-pyridine) units at both terminals were assembled, with the aid of a linear template molecule, into a discrete tubular complex with a length of 3.5 nm. The high stability and the well-defined structure of the coordination nanotube were revealed by NMR spectroscopy, cold-spray ionization MS, and single-crystal X-ray analysis. Guest lengths were discriminated by the tube: When the association of strandlike guest molecules, in which two biphenylene units are linked with an (OCH2CH2)n linker, were compared, the tube selectively recognized an appropriate guest whose length was comparable to that of the tube. Tetrathiafulvalene (TTF)-terminated linear guests were directly oxidized to TTF2+ in the tube, but reduced stepwise via TTF+ outside the tube.
